Description

[Technical Field]

[0001] The present invention relates to a cosmetic preparation comprising (a) sunflower seed wax, (b) one or more compounds selected from fatty acid esters having an average degree of ethylene oxide polymerization of 5 or less and polyglycerol fatty acid esters having an average degree of glycerin polymerization of 10 or more, and (c) an oil. [Background technology]

[0002] Various balm-type cleansers containing plant extracts have been proposed in the beauty industry and elsewhere (Patent Documents 1 to 3). Balm-type cleansers are not only formulated as cleansers, but also, because they are applied directly to the face or hands, are required to be easily scraped off in an appropriate amount, spread evenly on the skin, and blend well with the skin. However, conventional balm-type cleansers containing plant extracts have had problems with poor moldability and appearance, such as separation into two layers, unevenness, shrinkage, and lack of gloss. Furthermore, conventional balm-type cleansers containing plant extracts have had problems such as being too hard to scrape off in an appropriate amount, or being difficult to dissolve when applied to the skin. Furthermore, conventional balm-type cleansers containing plant extracts have had problems with poor blending with other cosmetics when applied to the skin, and leaving a sticky, tacky, or tight feeling after rinsing, resulting in a poor usability.
